Definitions

  • the present invention relates to a trigger-type liquid dispenser.
  • Such known trigger-type liquid dispenser comprises an injector body having an inverted L-shaped side shape, a nozzle head mounted at a front end of the injector body, a trigger hinged at a front portion of the injector body, a pump mechanism in the injector body, said pump mechanism including a plunger, and a coil spring for returning the plunger, which spring is made of metal.
  • a cover is mounted outside of the injector body.
  • the injector body includes a mounting cylinder and a suction pipe at its lower end.
  • the trigger liquid dispenser is mounted to a neck of a container storing liquid at the mounting cylinder.
  • the suction pipe is inserted into the container.
  • the conventional spring member made of synthetic resin has the following disadvantages.
  • a spring constant is uniform in whole of the spring member, it tends to concentrate an internal stress to a portion at which the spring member is fixed to the injector body. Thus, when the trigger is used above the setting times, there is a possibility of fatigue breakage. If a spring constant is uniform, internal stress is uniformly dispersed. Thus, if a spring constant varies gradually, a required spring elasticity may not be obtained, or an operating power is required too much.
